The Big Dutchman installation has been constructed according to the current state of
the art and all acknowledged regulations regarding technical safety. The installation is
reliable. Upon operation, however, dangers to life and limb of the user or third persons
or impairments of the system or other material property are still possible.
The system may only be mounted, attended, repaired and used:
•for due use
•in an excellent state from the safety and technical point of view
•by persons who are familiar with the safety regulations
In the event of special problems which are not described in detail in this manual, we
recommend to contact us for your own safety.
1.2 Designated use
The Big Dutchman fans must only be used according to their designated use. The Big
Dutchman fan EM50 serves the purpose of moving or circulating exhaust air in
livestock facilities.
Every other use is considered improper use. The manufacturer is not liable for any

1.11 Pollution abatement regulations
All works on and with the installation have to be carried out in compliance with the legal
requirements concerning waste prevention and proper recycling / disposal of waste.
Special care has to be taken when carrying out installation, repair and maintenance
works, as water pollutants like lubricating grease and oils, as well as solvent-containing
cleaning solutions are not to pollute the soil or get into the canalisation! These materials
have to be kept, transported, collected and disposed of in appropriate containers!
1.12 Waste disposal
After finishing the assembly or repair of this installation, dispose of the packing material
and remains which do not need to be further used according to the legal provisions for
recycling. The same applies to the component parts after putting the installation out of
service.
1.13 Notes for use
We reserve the right to modify the construction and technical data for reasons of further
development.

AirMaster EM50
Edition: 03/2015 M 2341 GB
2.2 Safety instructions when operating electrical appliances
You have to ensure that the system with the electrical appliances is operated and
maintained according to the electro-technical regulations.
Immediately switch off the installation in the event of malfunctions of the power supply
units. Use a bipolar voltage probe to make sure that the electrical equipment is not
alive.
Check the electrical wiring and cables for recognisable damage before putting the
device into operation. Replace damaged wiring and cables before taking the device
into operation.
Only use the fuses indicated in the circuit diagram. Immediately replace damaged
fuses. Never repair or bypass the fuses!
Never cover the electrical motor. This can cause high temperatures resulting in fire and
a break-down of the equipment.
The control box as well as the terminal and connector boxes of the installation must
always be kept shut.
Let damaged or broken plugs be replaced by an electrician.
Do not pull the plug from the socket at the flexible cable.
For the respective connections please see the enclosed connecting plan of the system
parts delivered.
Installation and work on electric components/structural groups may only
be carried out by qualified personnel according to electro-technical
regulations (e.g. EN 60204, DIN VDE 0100/0113/0160).
Dangerous electric tensions are bare in case of open control equipment.
Be aware of the danger and keep workers of other professions away from
the danger zone!
Do not install control devices directly in the house, but in the service room
to prevent corrosion caused by ammonia gas.
Warning
Never repair or bypass the fuses!
Damaged fuses have to be replaced with new fuses!

2.3 System safety instructions
2.3.1 Danger zone
The different areas of the Big Dutchman installations are characterised by different
types of construction.
There are several system parts that run out, rotate or slide that can increase the risk of
an accident when you are unaware of the type of construction.
There are hazard areas where a risk of injury exists
•due to rotating parts
•due to electrical current in case of non-reliable or defective switching-off of
overload current.
2.3.2 Entire system
•Parts lying about on the system and in its vicinity can cause persons to stumble
and/or fall and thus risk injuring themselves by contact with system components.
•Lack of knowledge about the structural design of the system can lead to injury.
•Parts lying about in or on the components can lead to serious damage of the
system.
Never reach into the running installation. Before reaching into the
installation, turn the system off and secure it against unintentional
actuation.
Assure yourself beforehand that the main switch is in the OFF position and
can not be put in the ON position without your knowledge.
After repair or maintenance work, never place any objects (e.g. spare
parts, replaced parts, tools, cleaning implements etc.) in the accessible
areas of the system or around it!
Make sure that all loose or replaced parts have been removed from the
system components before the system is taken into operation again!
Make yourself familiar with the construction of the system in sufficient
light! If this is not possible at site, get all available information on the
remaining dangers in connection with this system!
When working under the installation, always wear a safety helmet!
